I used the 

AWSSecurityTokenServiceClient sts_client = new AWSSecurityTokenServiceClient(),

and a default region (Global) was set authomatically. But this constructor is deprcated and the recommendation is to use: 

AWSSecurityTokenServiceClientBuilder.

I want it to use a default region, as well. I wrote:

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).build();

but I got an exception:

com.amazonaws.SdkClientException: Unable to find a region via the region provider chain. Must provide an explicit region in the builder or setup environment to supply a region.

I've never heard of the Global region, but to specify a default region with the new non-deprecated Builder method, you can use:

.withRegion(Regions.DEFAULT_REGION)

So your command would be:

AWSSecurityTokenService stsClient = AWSSecurityTokenServiceClientBuilder.standard() .withCredentials(new AWSStaticCredentialsProvider(awsCredentials)) .withRegion(Regions.DEFAULT_REGION.getName()) .build();

FYI - in my version of the Regions enum, DEFAULT_REGION is US_WEST_2. Don't forget to

import com.amazonaws.regions.Regions;

EDIT: It may be useful to know that it doesn't matter what region you specify. The generated STS credentials can be used in all regions (so they are 'global' in a sense).
